Nihon Kohden is Exclusive Distributor of ZOLL AutoPulse in Japan

May 24, 2006—CHELMSFORD, MASS.—ZOLL Medical Corporation (NASDAQ: ZOLL), a manufacturer of resuscitation devices and related software solutions, today announced a five-year exclusive agreement with Nihon Kohden Corporation to market and sell the ZOLL AutoPulse® Non-invasive Cardiac Support Pump in Japan, to commence upon regulatory approval by the Japanese Ministry of Health, Labour and Welfare. With annual revenue of approximately $790 million, Nihon Kohden is one of the top 100 companies worldwide selling medical equipment, and one of the top 10 companies specializing in medical devices.

According to Richard A. Packer, President and Chief Executive Officer of ZOLL, “Nihon Kohden sees the AutoPulse as an innovative product that can help improve patient care. This exclusive agreement provides significant revenue opportunity for the AutoPulse in the world’s third-largest economy. We are confident that Nihon Kohden, with its 650-person direct sale force, can help drive adoption of the AutoPulse inJapan.”

Commenting on the market potential of the AutoPulse, Mr. Packer continued, “Healthcare organizations in Japan are accepting of the concept of mechanical CPR because other devices that automate the CPR process have been in Japan since 1988. Consequently, more organizations understand the benefit, and are more likely to have allocated capital for such products. Since we believe that the AutoPulse is a more effective method of automating CPR delivery, and that the medical community understands the benefits, we anticipate that Japan will adopt the AutoPulse, once it is approved.”

The Japanese market for medical devices, already the world’s second largest, continues to expand as Japan’s population ages faster than that of any other developed country. According to the U.S. Department of Commerce, U.S. companies sell $5 billion worth of U.S.-made medical devices and supplies annually in Japan’s medical device market, which has a total annual value of approximately $20 billion.
